Hades
| Pop | 22.36 |
|---|---|
| Vit | 25.70 |
Hades is a high availability (HA) data source. This HA data source contains two other data sources: the main one and the failover one. The HA data source exposes one of them at a time and can automatically switch between them when certain conditions are met. These conditions are highly configurable. By default, when the main data source is overloaded, the failover data source is used. The load of a data base is determined on the basis of the average execution time of some configurable SQL statement that is examined periodically. The HA data source exposes through JMX its state and also operations for manual switching between the two contained data sources in case automatic switching must be suppressed for some reason.

Orient Key/Value Server
| Pop | 49.09 |
|---|---|
| Vit | 2.70 |
Orient Key/Value Server is based on the Document Database technology and is accessible as an embedded repository via Java APIs or via HTTP using a RESTful API. It uses a new algorithm called RB+Tree, derived from the Red-Black Tree to maintain tree balance, and from the B+Tree storing the links to records in pages to optimize memory consumption and loading time. Orient Key/Value Server scales out very well in a cluster with thousands of running machines: Orient will divide the load among all the nodes. Clustering, by default, works in auto-discovery mode: when a node starts, it attaches itself to the cluster if one is available. When a node goes down, the cluster automatically rebalances itself.

OrientDB

|---|---|
| Vit | 15.64 |
OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.

Generic Repository

|---|---|
| Vit | 1.71 |
The Generic Repository (grepo) is a framework for Java which allows you to access (database) repositories in a generic and consistent manner. Using grepo, it is generally no longer required to provide all the boilerplate code which is necessary in order to access (database) repositories from Java. All you have to do is write appropriate database code (queries, procedures, functions, etc.), an appropriately annotated Java interface, and very little Spring configuration.

| Vit | 5.89 |
Querydsl is a framework that enables the construction of statically typed SQL-like queries. Instead of writing queries as inline strings or externalizing them into XML files, they can be constructed via a fluentDSL/API like Querydsl. It supports JPA, JDO, Java Collections, SQL via JDBC, Lucene, and Hibernate Search.
